Data Myths

  1. 1. Data is information. Organizing our information makes it much easier to understand. Teacherswho use their data or student feedback to inform instruction are more apt to make sounddecisions. And as accountability measures increase, so does the likelihood for error andmisguided practices.Oftentimes, errors in judgment or the evaluation process occur as a result of misinformation andpoor observations of teaching and learning. The following are four of the most persistent andprevailing inaccuracies:#1 The responsibility is all yours.Student performance results are often tied to a specific subject matter or content area. However,teaching and learning cannot be attributed to the efforts of one individual. In fact, educators whounderstand that factors contributing to learning are numerous and require a collaborative effortare more likely to get positive results. The shared responsibility for understanding data and itsimplications for instructional decision-making lies with state/district-level instructional leaders,school-based administrators, and teacher teams alike. Targeted and informed decisions beginwith a comprehensive understanding or ‘big picture’ of learning goals and ultimately narrow inscope.#2 If it hasn’t been recorded, then it doesn’t count.There is a growing belief that every piece of data or student feedback must be recorded before itcan be considered useful. However, research indicates that the most effective teachers use bothformal and information observations of data to drive instruction. Data comes in a wide variety offorms including (but not limited to) anecdotal records, progress monitoring assessments, unittests and even verbal responses to questioning. The most effective teachers know when to recorddata and what data requires formal observation.
  2. 2. #3 We must use everything.Educators who are selective in their determination of which data access points to consider arebetter informed. We are constantly bombarded with information and not all of it is useful.Moreover, students sometimes respond or behave in a manner inconsistent with their actuallevels of performance. Effective teaching practice includes a heightened sense of awarenessmatching ability with expected levels of performance. Such keen awareness is likely to helpeducators better analyze information and use it to make sound instructional decisions.#4 "Lets agree-to-disagree."The most prevailing—and probably most damaging—misuse of data is the inaccurate analysis ofinformation or student feedback. When professionals collaborate to analyze data they must havea common understanding of what the information reveals. Consider this-Three teachers meet at the onset of the school year in order to review their students’ performanceon a state-level assessment. The assessment describes student performance in terms of levels(e.g., level 1, level 2, level 3) with a predetermined score for proficiency. Each teachers analysisis centered on his or her response to one question:What does an achievement level 1 indicate?Multiple responses to this question may indicate a misinterpretation of the data. In turn, this islikely to prevent an accurate analysis. Professionals may disagree on the causes or factors thatattribute to one score or another or even the most appropriate next steps. However, it is criticalthat all parties begin with a solid and unifying understanding of individual data points to preventthe likelihood of misguided instructional practices.Sources Coyne, M. (1997).
